This function provides multivariate and univariate Wald tests for combinations of parameters from `hlme`

, `lcmm`

, `multlcmm`

or `Jointlcmm`

models.

1 |

`Mod` |
an object of class |

`pos` |
a vector containing the indices in Mod\$best of the parameters to test |

`contrasts` |
a numeric vector of same length as pos. If NULL (the default), a simultaneous test of the appropriate parameters is realised. If contrasts is specified, the quantity to test is the dot product of pos and contrasts. |

`name` |
a character containing the name the user wants to give to the test. By default, the name's test is the null hypothesis. |

`value` |
the value(s) to test against. By default, test against 0. |

If contrasts is NULL, the function returns a matrix with 1 row and 2 columns containing the value of the Wald test's statistic and the associated p-value.

If contrasts is not NULL, the function returns a matrix with 1 row and 4 columns containing the value of the coefficient (dot product of pos and contrasts), his standard deviation, the value of the Wald test's statistic and the associated p-value.
